PATENT 1 'FFECE PETER SWEENEY, OF NEW YORK, N. Y., ASSIGNOR TO ROBERTSOMERVILLE, OF SAME PLACE.

IMPROVEMENT IN Q AR=AXLE LUBRICATORS.

Specification forming part of Letters Patent N 0. 175,779, dated April4, 1876; application filed January 21, 1876.

To all iuhom it may concern:

Be it known that 1, PETER SWEENEY, of

the city, county, and State of New York, have invented a new and usefulImprovement in OarAxle Lubricators, which improvement is fully set forthin the following specification, reference being had to the accompanyin gdrawing, in which- Figure 1 represents a longitudinal section of myimprovement. Fig. 2 is a cross-section.

Similar letters indicate corresponding parts.

My invention relates to'certain improvements in lubricators forcar-axles; and consists in an absorbent pad which is constructed ofalternate strips of felt and rawhide, such strips being fastenedtogether, while the whole is adapted to be placed within a car-axle boxin such a manner that the axle bears on the edges of the rawhide strips,and by these means I obtain a lubricator which is compact and durable,and one which has a very efi'ective lubricating-surface.

In the drawing, the letter A designates a series of felt strips, and Bare strips of raw hide composing my lubricator. These strips A B areplaced side by side and alternate with each other or, in other words,the felt strips A are separated from each other by the strips B ofrawhide. The felt strips A are intended to absorb the lubricatingsubstance contained in the axle-box O, in which my lubricator may beplaced, and to convey such substance to the axle D, while the office ofthe strips of rawhide B is, in part, to support the felt strips in avertical position. Any other absorbent material may be substituted forthe felt, and since rawhide has the property of absorbing oil or otherlubricators to a certain extent, while it retains its hardness anddurability, a lubricating-pad is obtained which possesses greatadvantages. The strips A B are fastened together in any suitable manner,and I have in this example employed for this purpose bands at a of sheetmetal, which pass transversely under the strips, and which are securedto plates E E, placed parallel to and exterior of the strips. To thebands at a are added one or more bolts, F, which are made to passthroughthe several strips, so as to hold them firmly together irrespective ofthe bands. The strips A B, when fastened together, rest on springs G G,which, in this example, are attached to the connecting-bands a a. Theabsorbent strips A are made of a less width than the rawhide strips B,the width being such that the absorbent strips may be made to projectdownwardly between and beyond the connecting-bands a a, as

shown, while the height of the rawhide strips B is greater than that ofthe absorbent strips A, so that only the edges of the rawhide stripscome in contact with the axle when my lubricator is placed in the box 0in such a way that the strips occupy a vertical position.

When my lubricator is placed in position the axle D bears on the rawhidestrips B, which are kept supplied with lubricating ma terial by theabsorbent strips, and consequently a very effective and durablelubricating-surface is presented to the axle, while, moreover, mylubrica-tor has a compact form and can be easily handled.

My lubricator may be placed within the axle-box in one section in casethe opening in the box is sufficiently large to permit of itsintroduction; or it may bemade in two or more sections, each smallenough to be introduced into the axle-box.

What I claim as new, and desire to secure by Letters Patent, is-

A lubricator for car-axles, constructed of alternate strips A of feltand strips B of rawhide, or their equivalent material, such strips beingfastened together and composing an absorbent pad, substantially asdescribed.

In testimony that I claim the foregoing I have hereunto set my hand andseal this 6th day of January, 187
